A modularly built bisubstrate inhibitor, the natural product pepticinnamin E (shown on the right) was sythesized for the first time. In the case of in vitro assays it inhibits the enzyme farnesyltransferase with respect to both the peptide substrate and farnesylpyrophosphate (KI = 30 and 8 μM, respectively). The inhibitory activity is decisively influenced by the central tripeptide unit and the absolute
首次合成了模块化构建的双底物抑制剂,即天然产物Peptininnamin E(如右图所示)。在体外试验的情况下,它相对于肽底物和焦磷酸焦磷酸酯均抑制法呢基转移酶(K I分别为30和8μM)。抑制活性决定性地受中央三肽单元和掺入其中的非蛋白质氨基酸的绝对构型的影响。
